I am looking for an experienced iOS developer to build a replay/backtest tool for MT5 Mobile on iOS, or alternatively, a separate iOS app that looks and functions exactly like MT5 Mobile. The goal is to replay historical market data (XAUUSD+, Gold) while allowing manual trading exactly like a live account, for strategy testing and trading video creation. The chart must look identical to a live MT5 chart, with no visible replay elements. Core Features Symbol: XAUUSD+ (Gold) Real historical market data, adjustable delay (1 hour up to 4 weeks) Replay mode: Play, Pause, Rewind/Fast-forward, adjustable speed Works on all MT5 timeframes Manual paper trading (Buy/Sell, multiple positions, live-like behavior) Add indicators and drawing tools (as in MT5 Mobile) No extra panels, no backtest marks UI/UX identical to MT5 Mobile iOS Important MT5 Mobile iOS only (no desktop solutions) No real-money trading, no broker connection Replay must not be identifiable as replay Implementation Options Option 1: Solution directly within MT5 Mobile iOS (if technically possible) Option 2: Separate iOS app with exact MT5 Mobile look & behavior
